The news behind the numbers.

Beginning of the end. AMC's Mad Men opened the first half of its final season Sunday with 2.3 million viewers, a 32% drop from the 3.4 million who watched Season 6 start last year and the least-watched premiere since Season 2. Other premieres included: Showtime's Nurse Jackie (751,000 viewers), Californication (640,000) and Years of Living Dangerously (294,000) on Sunday; two episodes of OWN's For Better or Worse (931,000 and 917,000) on Wednesday; and two episodes of Discovery's Boss Hog (1.1 million and 917,000) on Friday.

March Madness brings April title. CBS' coverage of Monday's NCAA men's basketball championship, which ended with Connecticut beating Kentucky, attracted 21.2 million viewers, down from the 23.4 million who watched the title game a year earlier. On Tuesday, 4.3 million watched Connecticut triumph again, beating Notre Dame for the women's national basketball championship on ESPN.

Seasonal goodbyes. FX's Justified attracted 2.4 million viewers for its fifth-season finale Tuesday, up a bit from the 2.2 million who watched last year's closer. Other finales included: Discovery's Amish Mafia (2.5 million) on Tuesday and USA's Suits (2.4 million) on Thursday.

Film funk. The MTV Movie Awards, which gave its big award to The Hunger Games: Catching Fire, averaged 2.8 million viewers on Sunday, down from 3.8 million in 2013 when it moved to the earlier, pre-summer-season date and honored The Avengers. Simultaneous broadcasts on sister networks MTV2, VH1 and Logo brought the total to 3.6 million, well below the 4.8 million watching across the networks in 2013.
